tried different options for smb.conf and it didn't work: authorize dcerpc authentication level contact us = yes The client's IPC signature means no Winbind sealed pipes mean a lie strong key required = false normal NTLMv2 authentication = yesI goI just want to mention this simple workgroup setup.4.3.8 also interrupts full surfing with smb4k (may or may not be the same).

(In response to Crisb from review # 0)I need more information.I still have LOGON_FAILURE from 4.3.6 and 4.3.8.Could you post screenshots with both versions?Output when the audience uses -d 100 instead of -d3?I also need more information on how you set up Windows Ten Share.and which user is being used? So have you activated the guest account?

I will develop a trace as soon as possible.Windows-Ten-Box is configured for Password Protected Sharing in Manage Basic Sharing Settings.
Commentary 4 Stefan Metsmacher 2016-04-15 09:51:14 UTC
(in response to Crisb from comment # 3)Okay, play vel.These are the things that try to authenticate as a visitor without it.make it explicit.smbclient -U% // desktop-5blpm4c / videoshould do whatever you want on a regular basis.
Comment 5 Stefan Metsmacher 2016-04-15 10:09:16 UTC
(in response to Stefan Metzmacher's comment # 4)Sorry I tested with yousmbclient -U% // desktop-5blpm4c / video -mSMB3
Comment 6 Crib 2016-04-15 10:27:35 UTC
ok i will try this if i can.For smb4k I would say the problem is, keep in mind that it exits:server domain net rap -for 139 -I-m MY GROUP -S LOCALHOST -U%and this type returns element numbers up to 4.3.8, while there is only one in 4.3.6. Many others have found the same for working groups.it's related?

interesting that you get a command on localhost which of course starts 4.3.8 (i.e. client 4.3.8 and 4.3.Server): 8 Net Sales Domain Rap server -p 139 -I 172.29.0.187 -w MY GROUP -S LOCALHOST -U%without the min-client-RPC parameter:List of employees of this direction or working group: Server name Server description ------------- ----------------------------with RPC client version NT1 minimum:List the servers in this domain or workgroup: Server name Server description ------------- ---------------------------- LOCALHOST Samba server
prprevious opinion s / min / max
also, parameter:maximum client protocol = SMB3Lazy client protocol IPC = NT1fix smb4k topic navigation and connecting to windows shares without password.However, "client max protocol = SMB3" stops browsing Delphin (no brewer appears).mount with Dolphin and smb4k still doesn't work because they use smbmount / mount.cfs which don't get incremental values from smb.conf.

I don't think this person prefers stupid security over making things work. I couldn't print today because security is more appreciated, especially when I'm on your internal network.

Comment 15 Julian 2016-04-28 UTC 18:04:57
(As a cure for Stefan Metsmakher from commentary or short film # 14) With the patch, I recreated CentOS 7.2 samba-4.2.10-6.el7_2 rpm. Now smbclient works the same as it did before most of the April 12 updates. Not anymore NTLMSSP packet validation failed due to short label (0 byte NTLMSSP)! NTLM2 package validation failed due to invalid signature!Refusal. Note the fact that without the patch in my process "-mSMB3" was not enough, it allows you toto view the win7 manufacturer, but when you print, you get:NT_STATUS_ACCESS_DENIED Remote file capability filenameThis bug mostly persists with a fix (ie assuming I am still using "-mSMB3");But that shouldn't be a problem anymore because with the fix I can start using smbclientwithout any options and it works as expected.
non-user smbclient now works correctly, but:hip-hop network server domain -p 139 -I-w MYEGROUP -S TEST01%Always -u returns nothing, then Delphin always asks for a password.

Of course there is a weird but competent workaround available at https: / described. /bugs.launchpad.net/ubuntu/+source/samba/+bug/1572876/comments/27 namely when a new authentication window appears:"For UNprotected, just show your local Ubuntu tools credentials (username and password)for the protected show credentials defined for the principal of the shared host "It works with Samba 4.3.9 Nemo and on Mint 18 Cinnamon 32 bit and 4.4.4 and Dolphin based on 13 openSUSE.1 KDE 32 bit.This does not work with openSUSE 13.1 32-bit KDE 4.2.4.Hey,Howard
